Agua Fresca de Pepino

Serve this refreshing cooler on a hot day-it's perfect with spicy Mexican food. Because we only include a tiny amount of seeded serrano pepper, the beverage doesn't become very spicy but picks up the "green" vegetal flavors of the pepper. Use the remaining serrano pepper in your favorite salsa recipe, or toss it into a lime-based salad dressing with cilantro.
